JAR AND CLOSURE THEREFOR.

Application filed February 14, 1919.

To all whom it may concern.

Be it known that I, QUINCY A. GATES, a citizen of the United States,residing at Vilkes-Barre, in the county of Luzerne and State ofPennsylvania, have invented certain new and useful Improvements in Jarsand Closures Therefor, of which the following is a specification.

This invention relates to storing vessels, such as fruit jars andclosures therefor.

The object of the invention is to provide a simple and eflicient vesselof this character, the cover of which is secured bygiving it a slightturn whereby it is locked to the vessel.

Another object is to provide a vessel and cover of this character with asealing groove or space formed between the perimeter of the cover andthe inner face of the vessel to receive the sealing material, whichperforms the double function of an auxiliary air excluder and anindicator to show whether the contents remain intact.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope ofwhat is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 represents a plan View of theupper portion of a jar constructed in accordance with this invention andhaving this improved closure shown applied and in locked position,

Fig. 2 is a transverse vertical section taken on the line 2-2 of Fig. 1,

Fig. 3 is a plan view with the closure shown disengaged ready forremoval,

Fig. 4 is a detail section taken on the line 4-4 of Fig. 3.

In the embodiment illustrated, a storing vessel in the form of a glassjar 1 is shown, the mouth of which has an annular seat in the form of aledge 2 on its inner face with- Specification of Letters Patent.

the like, of greater length than width and of a diameter slightly lessthan that of flange 3 being designed when in operative position to reston seat 2. This cover 5 is provided at diametrically opposite points onits upper face with beveled side portions 6 which incline graduallyupward toward their opposite ends to form cam edges 6 for interlockingengagement with the overhanging lips 4 when the cover is turned so thatthese edges pass under lips.

This cover 5 has upstanding lugs 7, two of which are preferably shown,and which are designed as finger grips to assist in turnmg the cover tolock or unlock it. The cover is also provided with stops 8 for limitingthe turning movement when looking the cover.

By making the cover cam-shape and of less diameter than flange 3 a spaceis formed around the cover between its perimeter and said flange asshown at 9 which is designed to receive a sealing substance perferablyparaffin which when poured into said space forms a perfectairtightconnection between the closure and the jar, and should a rubber gasketbe used, it may be placed on seat 2, but it is not necessary.

The short sides or beveled portions 6 of cover 5 afford ample space forthe positioning of the cover on ledge 2, permitting it to pass the lips4 as is shown clearly in Figs. 3 and 4 and enlarging the sealing face 9at diametrically opposite points 10, thus permitting the parafin to bepacked tight on opposite sides of the cover and between the long endsthereof. When the cover is positioned as shown in Fig. 3, to lock it, itis given a slight turn toward the right, which causes the cam-like faceof the side portions 6 to pass under lips 4 and securely lock the coveron the seat, the projections 7 facilitating this turning operation.

When the top has been locked in the manner above set forth, the paraflinor other sealing substance is poured into the space 9 and completelyseals the jar.

When it is desired to remove the closure, the knobs or projections 7 aregrasped and the closure turned toward the left until brought into theposition shown in Fig. 3, when it may be readily raised from its seatand taken off, it being understood that the turning operation will breakup the parafiin or it may be pried from or otherwise loosened in thespace if found necessary.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains and while I have described theprinciple of operation of the invention together with the device which Inow consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative and that suchchanges may be made as are within the scope of the claimed invention.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

1. A jar having an annular seat in the neck thereof, lip projectionsover and above the seat, and a closure body of greater length than widthmounted to-turn within the annular seat with its long sides normallyengageable under the lip projections to prevent withdrawal of the coverand its short sides spaced inwardlv from the lip projection to permitwithdrawal of the cover when the long ends are moved from beneath thesaid projections.

2. The combination with a jar having an annular ledge or seat formed inthe neck thereof and lip projections overhanging the said ledge, of acam shaped cover of less diameter than the seat to provide a sealingspace when inserted into the said seat, said cover being provided withbeveled side portions for enlarging the space at opposite points, andmeans for moving the cover into engagement with the lip projections forlocking the plate to the jar.

In testimony whereof I affix my signature in presence of two witnesses.

QUINCY A. GATES.
